Detailed Description

Support for DNG camera color profile information. Per the DNG 1.1.0 specification, a DNG file can store up to two sets of color profile information for a camera in the DNG file from that camera. The second set is optional and when there are two sets, they represent profiles made under different illumination.

Profiling information is optionally separated into two parts. One part represents a profile for a reference camera. (ColorMatrix1 and ColorMatrix2 here.) The second is a per-camera calibration that takes into account unit-to-unit variation. This is designed to allow replacing the reference color matrix with one of one's own construction while maintaining any unit-specific calibration the camera manufacturer may have provided.

See Appendix 6 of the DNG 1.1.0 specification for more information.
